To find the mean, add the numbers and divide the sum by the number of addends. \r
\n" ); document.write( "\n" ); document.write( "The median is the middle number in a data set that is ordered from least to greatest. \r
\n" ); document.write( "\n" ); document.write( "When there are two middle numbers, the median is the mean of these two numbers.\r
\n" ); document.write( "\n" ); document.write( "example:\r
\n" ); document.write( "\n" ); document.write( "\"13\", \"18\", \"13\", \"14\", \"13\", \"16\", \"14\", \"21\", \"13\"\r
\n" ); document.write( "\n" ); document.write( "The mean is the usual average, so I'll add and then divide:\r
\n" ); document.write( "\n" ); document.write( "\"%2813+%2B+18+%2B+13+%2B+14+%2B+13+%2B+16+%2B+14+%2B+21+%2B+13%29+%2F+9+=+15\"\r
\n" ); document.write( "\n" ); document.write( "The median is the middle value, so first I'll have to rewrite the list in numerical order:\r
\n" ); document.write( "\n" ); document.write( "\"13\", \"13\", \"13\", \"13\", \"14\", \"14\", \"16\", \"18\", \"21\"\r
\n" ); document.write( "\n" ); document.write( "There are nine numbers in the list, so the middle one will be the \"%289+%2B+1%29+%2F+2+=+10%2F+2+=+5\"th number:\r
\n" ); document.write( "\n" ); document.write( "\"13\", \"13\", \"13\", \"13\", |\"highlight%2814%29\"|, \"14\", \"16\", \"18\", \"21\"\r
\n" ); document.write( "\n" ); document.write( "So the median is \"14\".
\n" ); document.write( "
